Harvey, Rochester, N. Y., assignors to Eastman Kodak Company, Rochester, N.`Y., a corporation of New Jersey Application July `S, 1957, Serial No. 676,31@ Claims. (Cl. 21o-#22) film strip shows four exposures or groups of images, each group having four identical images varying only in the degrec of exposure. lt is necessary to select the best transparency or imagefrom each group of image areas taken and mount it in a suitable iilm mount for projecting or printing. The film mount for receiving the transparency is of the normal type as shown in Fig. 11 formed from a single piece of cardboard that is scored along its center line to provide two `hinged fiaps which are adapted to be arranged in overlapping relation with the transparency positioned or sandwiched therebetween. The flaps are provided with registering apertureswhich are of sufficient size to frame ,theimage area yof the transparency. The balance of the transparency extends beyond the edges of the apertures and is surrounded by an adhesive spacer elementsecuredto the marginal edges` of one of the iiaps. The flaps are -of larger dimensions than the transparency so as to extend beyond all sides of the latter as is well known.` When film transparencies are mounted within a film mount of the foregoing type, it is necessary to tack the transparency in an operative position in the transparency receiving area vframed by the spacer element before the mount is folded and sealed. The tacking is necessary `to assure that the entire picture-bearing area of the transparency is viewable through the apertures and to eliminate the possibility of an undesirable portion of the transparency `beyond the picture area appearing in the aperture viewing area. The tacking also eliminates any possible twisting or skewing of the transparency prior to sealing which would otherwise result in improper orienta tion of the transparency with respect to the apertures.

Therefore, one of the objects of the present invention is to provide a device adapted to simultaneously sever a selected `film transparency and tack the severed transparency to a 'film mount. t

Another object of the invention is the provision of an improved film mounting device having film orientation means for properly positioning the film thereon.

One more object of the invention is to provide an improved film mounting device having guide means for properly guiding the film mount into one of several transparency receiving positions.

Another object of `this invention is the provision of an improved film mounting device adapted to sever a selected transparency or image area from a group of image areas on` a film strip without moving the film strip in the mounting device, assuming that the film strip is initially positiloned with the image areas in a mounting position in the film mounting device.

further object ot the invention is to provide a film NUnited States Patent if l of the bearing posts 2li to pivotally urge the bracket 22 2 mounting device of simple design, constructed of few parts, thoroughly reliable and efficient in operation, and economical in manufacture.

Still another and more specific object of this invention is to provide a film mounting device having a beveled cutting die adapted to simultaneously lsever a selected film transparency, and urge the edge of the transparency into engagement with the film mount to tack the transparency thereto.

Objects and advantages other than those set forth above will be apparent from the following description when read in connection with the accompanying drawings, in which:

As shown in the drawings, this invention is embodiedin a mounting device 1 `having a base 2 and a pair of spaced apart ramemembers transverse to the base 2 and integral therewith. The frame members 3 each have an elongated slot l near the upper end thereof extending in wardly from one side and forming upper and lower frame surfaces 5', 6 respectively parallel to the base 2. An anvil 7 of glass or any other transparent material adapted tov permit the operator to see therethrough is secured to the upper frame surfaces 5. A guide plate S as best seen in Fig. 6 having four openings 9 and a pair of transversely extending guide pins il is secured by any suitable means to the lower surfaces d of the frame members 3. A cutting die platen l2 molded as one piece has four cutting dies i3, each die shown in Fig. 7 as a continuous beveled knife defining a substantially square opening roughly corresponding to the size oan image area 14 of a film strip ifi. A diffusion screen lla of glass is mounted within each of the openings formed by the knives. The die platen l2 further has openings il for receiving the guide pins llt, and rods i8 as seen in Fig. l carried by the platen for connecting it to an actuatingdevice adapted to impart a reciprocal movement to the die platen l2 on the guide pins 1l.. The actuating device comprises hinged link members 31.9 connected to the rods tti at one end and to bearing posts 2i secured to the base 2 at the other end. A U shaped bracket 22 pivotally mounted on studs 23 shown dotted in Fig. l carried by the frame members 3 has links 2d connecting the ends of the bracket 22l to the hinged portion of the. link members 19. The bracket 22 further has a lever 25 secured thereto, which is provided with a handle 26. A spring 27 has one end connected to a pin 28 carried bythe bracket 22 and the other end secured to one assay/ts against the rod 13 causing the links 19 and 24 to move the die platen 12 downwardly into its lowermost or nonrnounting position as seen in Fig. l.

A strip, of thin. sheet metal', not shown, is wrappedv around. thefframe, members 3 and secured thereto by cap screws to partially enclose the actuating device' and'y die platen; 121. An illuminating lamp 29 is: carried by a suitable lamp receptacle 31: mounted on the base 2. and cen trally located under the die platenv 12 to illuminate the film 15 through the diffusion screens 16 so that it may be viewed through the glass` anvil 7.

A web of exposed film such as shown in Fig. 10 is positioned in the mounting device 1 on. the guide plate as shown in.v Figs. 3A and 4. The guide plate 8 hasY a shoulder 32. for receiving one edgev of the filmV 15, and the: other edge of the film bears: against a pair of leaf springs 33 mountedfonthe plate ti. A thin flexible lid 34 ofl metal or plastic is secured to the plate S with a portion thereof exten-ding over the shoulder 32m properly guide the film 1:3 between the, shoulder 32 and the springs 33. To facilitate rapid but not entirely accurate positioning of a group of transparencies or image areas 14 in the viewing area of the guide plate 8, the film 15 is moved along the guide plate until a tiducial mark Up along with an arrow which is provided on the lm for each exposure registers with a small window 35 in the die platen 12 and is illuminated through an illuminating rod 36 disposed below the window 35 as seen in Fig. 1. The diffusion screens 16 carried by the cutting dies 13 are provided with an inscribed line 37 as shown in Fig. 7 clearly visible by means of the illuminating lamp 29 to mark out the exact outer boundary of the transparency or image area 14 to provide an extremely accurate means for orienting the film transparency with respect to the cutting die members 13.

The guide plate 8 is provided with locating means comprising stepped bosses 38 for positioning a film mount 39, such as shown in Fig. 11, in the mounting device in one of four possible positions depending on which one of the four image areas 14 is to be selected and mounted. The film mount 39 is of a well known type as described earlier having an adhesive spacer element 51 surrounding a transparency receiving area S2. The film mount 39 further has a strip of pressure-sensitive adhesive S3 positioned parallel and adjacent to one edge of an aperture 43, although the adhesive may be placed directlyl onto the iilm strip. Two ofthe four possible positions 41 and 42 of the film mount 39 are indicated by dotted and broken lines respectively in Fig. 4. ln position 41, the boss 3S extends through one of the film mount apertures 43 and bears against two of the sides of the aperture 43 to Aprevent longitudinal movement of the mount 39. The mount is prevented from lateral movement by one edge of the boss 38 and a ange 44 carried by the plate. In position 42, the mount 39 is prevented from longitudinal movement by an upturned lip of the plate 3 and one edge of the boss 38 bearing against the end of the mount. Lateral movement of the mount 39 is prevented by a flange 45 similar to flange 44 and one of two V shaped guide members 46 mounted on the rear end of the guide plate S, the other guide member tending to hold the mount in its located position. The guide members 46 which are best shown in Fig. 3 have openings for receiving pins 47 extending from a bar 48 secured to the lip titl. A helical spring 49 is interposed between each guide member 46 and bar 48 to urge the members against the plate 8. The members 46 are V shaped to form cam surfaces for guiding one of the corners of the film mount 39I into the proper position between one edge of the guide member 46 and the frame member 3.

In the operation of this invention, an electric cord, not shown, connects the lamp 29 to a suitable power supply to illuminate the lamp. A strip of exposed film 15'such as shown in Fig. 10 is threaded onto the guide plate 8 with one edge of ther film engaging the shoulder 4 32 under the lip 34 and the other edge bearing against the locating springs 33. The film strip 15 is moved along the guide plate 8 until the mark Up and arrow appears illuminated in the window 35. The operator then 0bserves the appearance of the group of four identical image areas 14, and selects the bestone of the group which we will assume is the lower right hand transparency as viewed in Fig. 4. The operator adjusts the film strip 15 until the image area 14 falls within the inscribed lines 37 of the screen 16. The film mount 39v is placed on the guide plate 8 in the position 41 with the transparency receiving area 52 positioned over and facing the lower right hand transparency 14. The lever 25 of the mounting device 1 is moved downwardly onto a transparency mounting position shown dotted in Fig. 1, initial movement of the lever causing the links 19 and 24 to move the die platen 12 upwardly into engagement with the film strip 15. Upon initial contact, the beveled cuttingknife 13 corresponding to the lower right hand transparency urges the film strip 15 into the transparency receivingy area 52 of the mount 39. The film strip is moved. into contact with the pressure sensitive adhesive 53,l and the film mount 39 against the glass anvil 7. Further upward; movement of the die platen 12 into the transparency mounting position causes the beveled knife 13 to sirnultaneously sever and tack the transparency 14 to the film mount 39 with the beveled portion of the-knife 13 urging; the edges of the transparency 14 inwardly as shown in Fig. 9 into engagement with the pressure sensitive adhesive 53. The beveled. knife 13 is forced partially through the film mount 39 which acts as the backing plate. The depth of penetration of the film mount 39 by the knife 13 is controlled by an adjusting screw 54 and lock nut 5S shown in Fig. 1 which provides an adjustable stop means for the handle 26, shown dotted.-

The stop means accordingly controls how far thedieA platen 12 may be reciprocally moved toward the anvil 7 when the lever is moved against the stop into thetransf parency mounting position. The remaining cutting knives .1.3 partially sever the corresponding nonselectedY transparencies 14 since a portion of the film mount 39 is interposed between a part of the remaining knives 13 and the anvil 7 to act as a backing plate as seen in Fig. 4. Since the adjusting screw 54 is adjusted so that the knives 13 do net contact the glass anvil 7 as seen in Fig. 9, the film strlp 15 in the absence of a film mount 39 is merely moved upwardly by the knives toward the anvil 7. Onl'y` those portions of the film strip 15 that are backed up. the film mount 39 are severed by the cutting, kniveslS, The cutting knives after severing the portions'of the film strip are forced partially'through the film mount wherever the knives are in engagement with the mount.

Although but one embodiment has been illustrated and described, it will be apparent to those skilled in theart that various changes and modifications may be made therein without departing from the spirit of the inventiony or from the scope of the appended claims.
